Feanor's Wrath

[mormegil]

He has power, both verbally and physically, and can inspire the best of the elves to rebel against the very gods. If that doesn't prove that he can unite the Noldor, then nothing will convince you.

But he did not convince all of the Noldor to follow him. Doubt among them had risen rapidly through their journey about Fëanor. They only didn't turn back because of their pride. After crossing the grinding ice I think that many would never accept Fëanor again. It was only through Fingon rescuing Meadros that they were united. What act would have been performed to attone for Fëanor. It would need to have been Fëanor instigating the act and I don't feel that he would.

Galadriel followed the Noldor but not Fëanor per se. She wanted to leave Valinor and saw her opportunity with Fëanor.

the best of the elves

Not in an attempt to argue semantics but the best how? The Vanyar were great in their own right and the Teleri in theirs. I don't know if it is correct to classify the Noldor as the best in using such a blanket statement.
